The OCCIware project aims at managing in a unified manner all layers and domains of the Cloud (XaaS), by building on the Open Cloud Computing (OCCI) standard. OCCIware Metamodel formally specifies the main OCCI concepts. Today a first EMF metamodel is defined that adds to OCCI new concepts such as Extension, Configuration, and EDataType, addressing some limitations of OCCI. This session highlights OCCIware platform two main components: - The OCCIware Studio Factory, allowing to produce visually customizable diagram editors for any Cloud configuration business domain modeled in OCCI using the OCCI Extension Studio, such as the flagship Docker Studio ; - The OCCIware Runtime, based on OW2 erocci project, including the tools for deployment, supervision and administration, and allowing to federate multiple XaaS Cloud runtimes, such as the Roboconf PaaS server and the ActiveEon Cloud Automation multi-IaaS connector. This talk includes a demonstration of the Docker connector and of how to use the OCCIware Cloud Designer to configure a real life Cloud application (a Java API server on top of a MongoDB cluster)'s business, platform and infrastructure layers seamlessly on both VirtualBox and OpenStack infrastructure.

7. OCCIware Factsheet
• 72 man year, 5,6m€ budget, sponsored by
French ministry of Industry over 2015-2018
• 3 academics, 5 companies, 2 associations
• To lower Cloud Computing adoption costs and
break up barriers between its various
implementations, layers, domains
- Especially Data Center, deployment, Big Data, Linked
Data
• By bringing to OGF's Open Cloud Computing
Interface (OCCI) the power of formal languages
and model driven engineering (MDE)

8. OCCIware Objective
Managing Everything as a Service in the clouds
Software as a Service (SaaS)
Big Data as a Service (BDaaS)
Linked Data as a Service (LDaaS)
Platform as a Service (PaaS)
Container as a Service (CaaS)
Infrastructure as a Service (IaaS)
DataCenter as a Service (DCaaS)
Network as a Service (NaaS)

10. Use case : Big Linked
Open Data Analytics –
monitoring energy
consumption

11. Monitor energy consumption
• Not only per user, or per utility provider
company,
• but per city, region, country,
- and per activity, usage, number of
children, amount of hair on feet would
most probably help also.
Multi-point of view data... that calls for an
open world approach of data – that's Linked
Data.

12. Linked Data & Datacore
• Linked Open Data ? That's Open Data sets that can
be cross-queried because they have been
semantically reconciled together
• Enter Ozwillo Datacore :
- it holds data that is shared between applications of
the Ozwillo app store : geographical elements,
organizations, reusable app business data…
- it stores it in a shardable replicated MongoDB and
is built in Apache CXF / Spring & Java
- it provides it through a REST API that is both web-
friendly and semantic web-compatible thanks to
JSON-LD, and helps developers with a Playground.

13. Linked Data, as a Service

14. Linked Data as a Service
(LDaaS)
But not your dad's Linked Data. If you want it to save
the world, it has to scale up the whole way :
• at Infrastructure level - that's IaaS : provision
enough CPU & storage, for each city
• at Platform level - that's PaaS : deploy java code
and mongo replicated cluster shards on each of them
• at Software level - that's SaaS : configure Linked
Data governance i.e. models and kinds of use :
- high write, non-robust data collection (home
energy consumption sensor notifications)
- read/query-heavy data analysis (aggregation per
energy consumer, provider, city, region, country)

15. Linked Data – 3 target scenarii
3.2.1.

16. Quick demo – Docker
Studio, custom Linked
Data extension

17. Cloud Studio, with Docker

18. Custom Studio for LdaaS
(Linked Data as a Service)

19. Docker Studio
IaaS - Virtual Box machine

20. Docker Studio
IaaS - Open Stack machine

21. Docker Studio
… started !

22. Linked Data Studio
SaaS - Linked Data with
dedicated analytics entry point

23. Linked Data Studio
… using a specific mongodb
replica within its cluster !

24. Allowing to not hamper data collaboration
performance when aggregating energy
consumption - results shown here :
...by consumer
...by his city

25. Upcoming in OCCIware
- Studio : more generators & connectors, improve existing ones,
integrate simulator, decision-making tool…
http://github.com/occiware/ecore
- OCCI administration console's live functional testing Playground –
http://occinterface.herokuapp.com/
- Complete erocci-dbus-java bridge & HTTP bridge, so that Studio-
generated connectors can be deployed within the Studio, on erocci
or standalone indiscriminately
- Runtime : complete OCCIfication of ActiveEon's OW2 ProActive
Multi-IaaS connector and Linagora's OW2 Roboconf PaaS manager
- Develop specified OCCI monitoring solution
- Further use cases : Datacenter, Big Data, Deployment, Linked Data
- … and contribute back to OCCI 2.0 standard !
